Horse may sometimes not move when equipped with a saddle. It will not move at its current position and it will get stuck. I quit and come back to the world and the horse was moving again and can be ridden. When the game crashes or force quit while riding the horse or on a boat, the horse and boat would disappear. This could also occur during 2 player split-screen. The second player would have to leave the world then come back for their horse to move and be riddable again. The dissapeared horse happens when any player rides a horse or a boat with a saddle horse. I currently playing on PS4 bedrock when I witness this bug.
